[Bug 1875548] Re: Its not easy to determine how to skip the filesystem check

[Jay Michael]

Ubuntu 20.04.2 behaves the same way.

"quiet" kernel parameter seems to enable skipping the disk check:  With
"quiet" on the kernel command line, one of the few lines to appear on
the screen is "disk check skipped", and the boot completes noticeably
faster.  (35s instead of 55s, booting from an ISO file on a hard disk)

Title:
  Its not easy to determine how to skip the filesystem check

Status in casper package in Ubuntu:
  Fix Released

Bug description:
  I see that Live Ubuntu 20.04 is plagued by disk checking on boot.

  Not just with Live USB but with Persistent USB also.

  If not fast enough to cancel with ctl-c it starts on
  filesystem.squashfs and runs until over 90% complete.

  Very irritating. There have been quite a few complaints on Ask Ubuntu
  already.

  If it was just a run once it would not be so bad.

  Is there some way to get rid of this or is it a bug we have to live
  with?

  Perusing Ask Ubuntu everyday for many years I have never seen anybody
  ask for such a feature.

  A run once filesystem check might have its uses on a Live installer
  drive but is not needed on a Persistent utility drive.

  The only alternative I see is to use a Full install USB drive were
  automatic disk checking is not run.
